What the developers have to say:

Why Early Access?

“Our goal is to deliver more than just a playable game; we want to provide an experience that is truly engaging and polished. We believe that direct communication with our community is essential to refining the game’s direction and adding depth to the gameplay. We decided to launch in Early Access to gather valuable feedback in real-time and evolve the game together with our players.”

Approximately how long will this game be in Early Access?

“We expect the Early Access period to last approximately 1.5 to 2 years. During this time, we plan to continuously add new islands and diverse contents. We hope to release the full version once the game reaches a level of quality that satisfies both our team and our players through iterative updates and close communication.”

How is the full version planned to differ from the Early Access version?

“We plan to expand the explorable regions (islands) for the full release and aim to introduce new ecosystems to accompany them. Additionally, based on feedback collected during Early Access, we will improve system convenience (QoL) and introduce a wider variety of items for collection and crafting with even more depth.”

What is the current state of the Early Access version?

“Currently, all core survival and crafting systems—including building, farming, hunting, gathering, fishing, cooking, and costume crafting—are fully implemented and playable. You can already fully enjoy the game's fundamental gameplay loop. Moving forward, we plan to focus our updates on refining the details of each system and increasing the overall volume of content.”

Will the game be priced differently during and after Early Access?

“Yes, the price will increase upon the official full launch to reflect the newly added content and expanded features.”

How are you planning on involving the Community in your development process?

“We intend to share our development progress transparently through the official Steam forums and social media channels. We plan to use these platforms to provide the latest news on major updates and maintain consistent, active communication with our community.”
